SPECIFICATION forming part of Letters Patent No. 362,444, dated May3,1887.

Application filed October 21, 1886. Serial No. 216,883. (No model.)

To all whom it may concern:

Be it known that we, HENRY O. HART and HENRY Yon, both of Detroit, inthe county of Wayne and State of Michigan, have jointly invented acertain new and useful Improvement in Store- Service Apparatus, of whichv I the following is a specification.

Our invention relates to store-servlce sys tems 1n which a carrier runson. an overhead il way, supporting beneath it a detachable receptaclefor parcels or'other articles; and our object is mainly to providesimple and convenient means for raising and lowering the re- 11 ceptacleand for connecting it to and disconi 5 necting it fromthe carrier, andalso to provide certain improvements in the propelling devices whichmove the carrier upon the way.

Our invention consists in the noveldevices and combinations of devicesemployed by us a in accomplishing these objects, as hereinafter 2 5tion; Fig. 2, an enlarged elevation showing the carrier, detachedreceptacle, and elevator therefor; Fig. 3, a bottom view of the carrier.Figs. 4 and 5 are respectively sections of the connecting devices of thecarrier and recepta- 0 cle, showing different positions thereof.

Fig. 6 is a top View, and Fig. 7 avertical longitudinal section, of thecatch for holding the car rier; Fig. 8, a top view of the stop for theelevator-cord; Fig. 9, a cross-section of the standard, and""'Fig. 10 anelevation of a portion 40 employ.

,A is the main supporti11g-"standard,which is a'tube, and is preferablysupported froin'the ceiling, as shown.

B is the wireway, (l thecnrrier, and D the detachable receptacle.

The. elevator consists of a rod or bar, I), preferablyoi' flat form, asshown, which is placed within the hollow standard A, and, extendingbelow the same, is turned at a right 5o angle and extends outhorizontally under the wireway 13. Here there are v attached two pairsof upwardly-extending curved branch ing arms, FF, each f arm beingforked at its upper end, as seen at a a. To the upper end of bar E isattachecla cord, G, which passes out from the standard A through a slotand over a grooved pulley, I), placed in said slot. Above said, pulleyis placed a curved guardplate, a. For supporting these parts a sleeve orcollar, d, is placed upon the standard. At the lower end of thestandard. a sleeve, H, is coupled upon it, from which extends a plate,I. This plate has an aperture, 6, through it and a smaller connectedslot, f. (See Fig. 8.) Through this aperture the cord G passes, and thecord has upon it buttons of such size as to pass through c, but notthroughf. A part, h, slides upon the plate I, having a spring, h, formoving it in one direction. Sleeve H has a downwardly-extending finger,i, which acts in connection with certain parts on the elevator,hereinafter described, as a stop for said elevator.

Pivoted on alug on plate H is a dog, K, having a spring, is, attached toit. At 1, in its upper end, dog K is slotted, and a stationary pin, 1%,is provided to limit the movement of as to enter the eye a of plate1',Fig. 8, to.

guide the elevator in raising it. Also placed upon bar E is a turningdisk, M, l'iaving alternate deepnotches 0 and short notches o. A pawl,N, prevents the turning of the disk in one direction, but allows it toturnin the other. I

The carrier consists of a body, 0, suspended from grooved rollers 19 p,which run on wire 13.

Below the body 0 extend bell-mouthed tubes g q g, each of which has inone side two slots or openings,-the lower one, r, being narrower thanthe upper one, r.

The receptacle consists of a basket, I), pref- The lllitlllffiatlllflSof the propelling device :00

and catch for the carrier which we prefer to use are as set forth inpatents to R. A. Mc- Oarty, dated September 1, 1885. A forked arm, P,extends from standard A, having pulleys at its ends, and over thesepulleys, and also over a pulley near the top of the standard, passes acord, Q, having interpolated in it a rubber spring, Q. The cord liesin aloop on w1re B until it is caught by the projecting horn of the carrier.

The catch for the carrier consists of a plate, R, hinged upon thestandard, and having a spring-latch, u, with which thedownwardlyextending hook at end of carrier engages. The cord Q passesthrough aring or eye, e, of plate 1?, whose main aperture has aconnected slot, 12, extending from it. Cord Q has buttons to upon it,which are of such size as to pass through 0, but not through c.Heretofore in apparatus of this character only one eye 11 has beenprovided, extending from one side of the catchplate We provide two sucheyes, one 011 each side, (see Fig. 6,) whereby the cord may be broughtdown on the side which is more convenient for the operator, according tothe situati on in which the apparatus is placed. A set-screw,,w, isprovided for limiting the movement of plate It. S is a spring-buffer forrece1 v1ng the carrier and preventing it from striking the standard,which is desirable when the receptacle contains a heavy load.

It has heretofore been usual to pass the wire B through the mainstandard and attach it to the wall behind by a turn-buckle, so that itmight be tightened thereby. Since, however, we have the bar E within thestandard,we cannot conveniently do this, and we therefore provide thearrangement shown in Figs. 11 and 12. I A ring, 00, is bolted around thestandard, having lugs a7 00, one on each side. From these lugs screws yg extend to a clamp, T, in wh1ch the wire B is held by set-screws z 2.The standard is braced from the wall by stays 2, extending from eyesattached to ring so. The wire is tightened by screwing down the screwsy.

The operation of the apparatus is as follows: In Fig. l the receptacle Dis shown in the act of leaving the carrier 0 for the elevator E. In Fig.2 the receptacle is resting in the elevator below the carrier. to attachthe receptacle to the carrier and to propel the same upon the way, thesalesman,

cashier, or other operator draws down upon the cord G, thus raising theelevator E, with the receptacle supported upon it, until the arms 0enter the tubes q and the pawls t reach the slots 1', whereupon thesprings t throw the pawls out into the slots and the receptacle is heldthereby. The movement of the elevator is stopped by the finger tentering one of the short notches 0 of disk M, so that the pawlst cannotat this time pass the slots 0'. As the elevator rises, the arm Lentersthe eye a, which steadies and guides the elevator, so that the arms 0will certainly enter the tubes q. At the same time the disk M pushes theWVhen it is desired dog K aside against its spring 7:, the disk be ingitself prevented from turning by pawl N. The operator now permits theelevator to descend, leaving the receptacle suspended from the carrier,and as it descends the deg K turns the disk M the distance of one notch,and thus along notch, 0, is brought below finger 17, instead of a shortone, 0. To propel the carrier, the operator draws down the cord Qthrough one ofthe eyes 1), distending the spring Q until the righttension is produced in the spring, when he draws the cord into the slot12, and one of the buttons 20 engages therewith and moves the hingedplate R down, so as to release the carrier, whereupon the force of thespring Q acts to impel the carrier upon the. way. The elevatoris'allowed to descend a short distance only, far enough to clear thereceptacle, and itis then stopped by moving the cord G into the slot f,so that the button g comes directly beneath said slot, and the cord isthereby held, and itself holds the elevator at the point at which it isplaced. This movement of the cord moves the slide it back against itsspring.

It is preferred to have at the other end of the way B another apparatussimilar to this. \Vhen the carrier is thereby returned, it is caught bythe catch R. To detach the receptacle,-the cord G is drawn downslightly, when the spring-slide it pushes it out of the slot and keepsit in a central position. drawing down on the cord the elevator israised and catches the receptacle and continues to push it up, because,as just explained, the disk M has been turned so as to present a deep Onfurther ICO notch, o, to finger The pawl t is therefore therefore, ifthe cord is now released, the recep- I,

tacle-will be free to leave the carrier, and the elevator and receptacleare lowered to any desired point, where they may be stopped by stoppingthe cord G, as already explained. Such articles as are in the receptacleare then removed, or articles are placed therein. The receptacle may beallowed to remain on the elevator, or itmay be lifted off for thispurpose. I I
